To all whom 1' 1,. may concern Be it known that I, TIMOTHY C. Domain s,

a citizen of'the United States, and resident ofLos Angeles, Los Angeles county, Cali-' fornia, have made certain new and useful Inventions Relating to Repair Devices for Pneumatic Tires, 620., of which the following is a specification, taken'in connection with the accompanying drawlng, formlng part of the same.

This invention relates to repair devices securely hold it in position adjacent the puncture or blow-out, there being, if desired,

a suitable patch of reinforced rubber or the like inserted between the tire shoe and its inner tube to reinforce the parts and mini: mize abrasion.

In the accompanying drawing showing in a somewhat diagrammatic manner an illustrative embodiment of this invention, Figure 1 shows the repair device as applied to a pneumatic tire. Fig. 2 is an enlarged cross-section through the tire and device; and Fig. 3 is an enlarged perspective view of one of the anchor plates arranged for three chains. 7

In the illustrative embodiment of the in vent-ion shown in the accompanying drawing the pneumatic tire 3 is shown as oooperating in the usual way with the clencher rim 2 mounted on the felly l of the wheel. This shoe is shown as having a large puncture or tear 9' therein and the repair patch 4 of reinforced rubber or the like'is indicated as i-nserted wit-hinthe tire shoe -adjacent this puncture so as to reinforce the the at this point and prevent the inner tube 5 from coming intoinjurious contact with the roughened shoe at the puncture. The external repair device may asindica ted comprise the two anchor plates 8, p which may be formed of steel or other suitable material, and which are curved to closely conform to the adjacent surface of the tire and preferably provided with' relatively narrow centrally located holding on securing devices of any desired characterto have-corresponding holding action on any part of the wheel and which may each byein the formof a Specification of Lettcr's'Patent.

Application fl led september 18, 1911. Serial No. 649,933. i

" suitable anchor lip or hook 18 to engage and securely hold upon 'the inturned flange of the clencher rim when inserted between the shoe and rim when the tire is deflated. A series of flexible irregular shaped gripping securing or retaining members, such,- for instance, as the hardened steel curb chains 6 maybe connected with the anchor plates preferably in a detachable manner, as by the double attaching'hooks 7, one of which may be connected with each end of one of the chains 6 andprovidedwith ends 10 which may pass through suitable holes in the anchor plate and be bent around as indicated to securely hold the-parts together. Any desired number of such retaining membersmay be connected with a corresponding sized anchor plate, devices having two, three, four or more chains, each being useful for various/sized blow-outs and punctures, although for generalpurposes a four-chain repair device of this character has proved of general utility! or an incipient blow-out the tire chains may be applied alone after deflating the tire without the necessity of using an inner patch of any kind, the anchor plates being forcibly inserted in'ainy way between the tire shoe and clencher flanges on-each side of the tire and then on inflating the-tire in the usual way the chains and connected parts become considerably embedded 'inthe tire shoe so as to exert a strong retaining action thereon and not only prevent. excessive working or movement of the parts with respect tothetire underservice conditions, but also to minimize the normal resilient movement of this part ofthe tire sov as to correspondingly preventfurther tire damage.

By providing the anchor plates with narrow central-hooks or securin devices the platesare free to swing or oscillate slightly about such securing means as the connected chains move into contact with the road surface so as to furtherminimize working or cutting. In the case of' punctures especially when large rep'airdevices give-best results when'used inconnection with an-in ternal patch such as indicated, and in-this way a seriously damaged-tire can be quickly and easily repaired without expert assist; ance so as to secure hundreds of'milesot further service from-the the if necessary.

Indeed, it is possible thy-the 'use of several In repairing a weakened spot in the tire Patented June 24, 1913 such repair devices to use a pneumatic tire in which the shoe has been entirely severed in a more or less diagonal direction, while in the case of ordinary blow-outs the tire is so reinforced by the repair device that this portion of the tire is apt to outlast the other action to the vehicle because umping on the chains is thereby minimized. It is of course understood that the length of the retaining members may be readlly varied, for instance,"by removing the attaching hooks 7 and inserting them inanother link of the chains before again securin the hooks to the corresponding anchor plate and if desired the chains may be provided with one or more extra links beyond what are necessary for small tires, so' as to allow the effective length of the chains to be correspondingly adjusted and the repair device fitted to tires of different size.

This case contains subject matter taken from my co-pending application No. 623,613, filed April 27, 1911. 1

Having described this invention in connection with illustrative embodiments, forms, proportions, materials, and arrangements of parts, to the details of which disclosure the invention is not of course to be limited, what is claimed as new and what is desired to be secured by Letters Patent is set forth in the appended claims.

1. As a new article of manufacture, a tire repairing device comprising a plate adapted to lie in proximity to the tire alongside the rim and to detachably engage the latter, a similar plate adapted to lie upon the oppo site side of the same portion of the tire, engaging the rim in like manner, and a series of slightly separated chains passing around the exposed surface of said portion and having their ends detachably connected to said plates, respectively.

2. The combination with a wheel rim and a pneumatic tire thereon, of an internal-flexible patch for the tire, of a series of slightly separated chains connected with the rim upon opposite sides of the tire and passing around and binding closely that portion of the tire within which the patch lies; whereby the inner surface is protected and the body of the tire is held against material movement in any direction.

3. A tire repairing device comprising a relatively narrow plate adapted V to lie alongside the wheel rim, conforming to the adjacent surface of the tire, and provided with a central hook to pass inward alongdesirable movement.

side the tire and detachably engage the inturned rim flange, a like plate adaptedto be engaged in like manner on the'opposite side of the same portion of the tire, and a series of slightly separated chains having their ends in detachable hooked en agement pass over said portionsof the tire; w ereby both the tread and the lateral surfaces of the tire are indented and the parts of the tire within the chains are held against material movement.

with the plates, respectively anda a ted to 4. The tire repair device comprising a pair of anchor plates adapted'to coo crate with the opposite sides of the tire an each provided with holding means adapted to cooperate with the inturned flange of the clencher rim of the neumatic tire when in serted between the rim and tire, and a series of securing chains-connected to said anchor plates and adapted'to closely embrace and embed themselves in the resilient pneumatic tire under operating conditions. I
